Side-by-Side IQ Profile
The Weimaraner, a breed ranked #21 by Coren, demonstrates a robust cognitive toolkit. Their Problem Solving is rated 4/5, indicating a capacity for complex thought, adeptness at figuring out puzzles, and a drive to overcome obstacles to achieve goals. Training Speed, also 4/5, means they grasp new commands and routines with relative swiftness, often requiring fewer repetitions than many other breeds. Social Intelligence at 4/5 suggests a nuanced understanding of human cues and emotions, making them responsive and interactive companions. An Instinctive Drive of 5/5 highlights their profound inherent motivations, often geared towards tasks like retrieving or tracking, which fuels their engagement. Finally, their Memory at 4/5 ensures they retain learned behaviors and past experiences efficiently, building upon their knowledge base over time.
While not Coren-ranked, the Japanese Chin presents a different, yet equally valid, cognitive profile. Their Problem Solving scores 3/5, meaning they can navigate familiar routines and learn specific tasks, but might find novel, multi-step challenges less engaging or more difficult to decipher independently. Training Speed, at 3/5, indicates they are certainly trainable, but may require more patience, consistent positive reinforcement, and a clearer breakdown of tasks compared to breeds with higher scores. Social Intelligence, also 3/5, suggests they form strong bonds and understand their immediate human family, expressing affection and responding to familiar social cues, though perhaps less inclined towards broad social interaction with strangers. Their Instinctive Drive, rated 3/5, points to a lower inherent urge for complex work or high-energy pursuits, instead finding satisfaction in companionship and observation. Their Memory, at 3/5, allows them to recall routines and learned behaviors, albeit potentially with a need for occasional refreshers, maintaining a consistent daily structure.
Where Weimaraner Wins Cognitively
The Weimaraner's cognitive strengths are evident across nearly all measured dimensions, making them exceptional partners for dynamic engagement. Their 4/5 Problem Solving ability means they are adept at strategizing, whether it's figuring out how to open a gate or navigating a complex scent trail. This translates into a dog that enjoys mental challenges and can often "think through" situations independently, making them capable partners in sports like agility or obedience. Their high Instinctive Drive (5/5) is a significant cognitive asset, providing an intrinsic motivation to engage with tasks and learn, transforming potential energy into focused effort. This drive, combined with their 4/5 Memory, allows them to build vast repertoires of skills and knowledge, retaining complex sequences and commands over long periods, making advanced training achievable and rewarding.
Where Japanese Chin Wins Cognitively
While their scores are generally lower, the Japanese Chin possesses distinct cognitive advantages particularly suited to their role as companions. Their 3/5 Social Intelligence, while not overtly expressive, is finely tuned for close human relationships, allowing them to perceive subtle shifts in owner mood and respond with quiet empathy, excelling in creating a tranquil home environment. Their more moderate Instinctive Drive (3/5) means they are less prone to restlessness or destructive behaviors when not provided with constant high-intensity mental stimulation, a cognitive "win" for owners seeking a calm domestic presence. Furthermore, their cognitive profile makes them highly adaptable to quiet, predictable routines, where their 3/5 Memory and Problem Solving are perfectly adequate for navigating daily life without the need for constant novelty or challenge, reducing owner burden for complex mental enrichment.
Which is Easier to Train and Why
Based on their profiles, the Weimaraner is generally easier to train for complex tasks and a wider range of activities due to their 4/5 Training Speed and powerful 5/5 Instinctive Drive. They tend to pick up commands quickly and are highly motivated by purpose and reward, often excelling in structured training environments. Their eagerness to work and strong memory (4/5) make them responsive to consistent instruction, though their high drive also means they require firm, consistent guidance to channel their energy productively and prevent self-directed "problem-solving" that might not align with human expectations.
The Japanese Chin, with a 3/5 Training Speed and 3/5 Instinctive Drive, is certainly trainable but requires a different approach. They thrive on positive reinforcement, patience, and making training feel like a fun, low-pressure interaction rather than a demanding task. Their social intelligence allows them to respond to their owner's emotional state during training, but they may become disengaged if bored or overwhelmed. They may not learn as rapidly as a Weimaraner, often needing more repetitions, but their desire for companionship means they are willing to learn behaviors that strengthen their bond and contribute to a harmonious home life.
Which Suits Active Owners vs. Relaxed Owners
The Weimaraner is an ideal match for active owners who relish engaging deeply with their dog's cognitive and physical needs. Their robust problem-solving skills, strong instinctive drive, and quick training speed mean they thrive with consistent mental stimulation, structured training, and opportunities for purposeful activity like hiking, running, or dog sports. Owners who enjoy teaching complex tricks or participating in competitive obedience will find the Weimaraner a highly capable and enthusiastic partner.
Conversely, the Japanese Chin is perfectly suited for more relaxed owners who appreciate a gentle, observant companion. Their moderate instinctive drive and problem-solving scores mean they are content with a less demanding schedule of mental enrichment, finding satisfaction in quiet companionship, short walks, and familiar routines. Owners who prioritize a calm household, enjoy subtle social interactions, and are comfortable with a dog whose "work" is primarily being a loving, serene presence will find the Japanese Chin an excellent fit.
The Verdict
When seeking a highly engaged, intellectually driven partner for active pursuits and complex training, the Weimaraner's superior problem-solving, training speed, and instinctive drive make them the clear choice.
If your lifestyle calls for a tranquil, observant companion whose cognitive strengths lie in subtle social bonding and adaptability to a peaceful home, the Japanese Chin is the ideal selection.

Does a lower IQ score mean a dog isn't smart?
Not at all; it simply indicates a different cognitive profile. A 3/5 in problem-solving means a dog can still learn and adapt, but might not excel at novel, complex puzzles, preferring familiar routines. Every breed's intelligence is perfectly suited to its original purpose and desired companionship role.
Can a Japanese Chin participate in dog sports?
While not typically bred for high-intensity sports, a Japanese Chin can certainly participate in lower-impact activities like beginner obedience or trick training. Their social intelligence and desire for interaction can make these activities enjoyable, focusing on bonding rather than competitive drive.
How much mental exercise does a Weimaraner need daily?
A Weimaraner, with its high problem-solving and instinctive drive, requires significant daily mental stimulation, often 30-60 minutes of structured training, puzzle toys, or engaging activities. This prevents boredom and channels their cognitive energy into productive outlets, complementing their physical exercise needs.
